Troubleshooting
Heart-Leaved Curcuma problems — and how to fix them
Heart-Leaved Curcuma (Curcuma cordata) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Rhizome rot
Critical risk during winter dormancy if soil stays moist. Dry storage in frost-free conditions is essential.
Leaf scorch and browning edges
Caused by low humidity, draughts, or too much direct sun. Maintain high humidity and protect from harsh light.
Spider mites
Large leaves are attractive to mites in dry conditions. Mist frequently and treat with neem oil or insecticidal soap.
Bacterial or fungal leaf spot
Can develop if water sits on foliage in warm, stagnant conditions. Water at the base and improve air circulation.
Poor sprouting after dormancy
Needs warmth above 20°C to break dormancy reliably. Withhold water until leaf tips begin to emerge, then resume gradually.
